GAS-LIGHTING LANTERN.

- Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, ABEL WILSON, of the city of Philadelphia and Stateof Pennsylvania, have invented certain new and useful Improvements inLanterns for Lighting Gas; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawing and to the letters of reference marked thereon.

My invention relates to improvements in lanterns used by lamp-lightersfor lighting gas, and consists in attaching to the top of the body orcasing of the lantern a hollow perforated cone open at the top and abovethe latter a hollow corrugated or other suitably formed cone. Theinterior of the lantern communicates with the interior of I theperforated cone and the space between the two cones and with theexternal atmosphere.

My invention has for its object the instantaneous lighting of gas bysimply holding the lantern in such a position with regard to the openburner that the gas from the same may enter the openings between the twocones.

In order to enable others skilled in the art to make and use myinvention, I will now proceed to describe its construction andoperation.

On reference to the drawing which forms a part of this specification,Figure 1 is a sectional elevation of my improved lantern. Fig. 2 anexterior View of the same. Fig. 3 a sectional plan on the line 1, 2(Fig. 1); and Fig. 4: a view showing the position in which the lanternmay be held in order to ignite the gas.

Similar letters refer to similar parts throughout the several views.

A is the exterior casing of the lantern having any convenient number ofopenings at furnished with suitable transparent material. In theinterior of this casing a per forated metal cylinder B is so fitted thatthere shall be an air space between the two, the perforated cylinderbeing held in its proper position by means of springs (Z secured to theinterior of the outer casing. Attached to the perforated cylinder andresting with a projecting flange on the top of the exterior casing is ahollow cone C perforated at the sides and open at the top. Attached tothis cone is a corrugated hollow cone D, to this is secured a smallercor- 18,784, dated December 1, 1857.

rugated cone E, and to the latter a still smaller cone F, to which aswell as to the inner plate f is attached the ordinary lantern handle II.It will be observed that the openings formed by the corrugations of thethree cones E, F and G, communicate with each other and, through theopening on the top of the perforated cone D, with the interior of thelantern. On the top of the outer casing A are a series of openings h,the bottom of the casing having a similar series of openings z' and onthe bottom of the lantern are a series of openings j. The two formerseries of openings communicat- Ing with the space between the inner andouter casings and through the perforations of the inner casing with theinterior of the lantern, and the openings j communicating direct withthe same.

K is the lamp of the lantern furnished with a wick-tube 72 as inordinary lamps, to which it is in other respects similar with theexception of the hollow cone shaped projection L in the cover of whichis a minute orifice.

hen it is desirable to ignite the gas at a burner, the cock of thelatter is opened and the lantern is held in about the position shown inFig. 4:, that is with the open space between the perforated cone O andcorrugated cone D directly above the burner, when ignition immediatelytakes place. This effect is produced as follows :\Vhen the lamp of thelantern is ignited the air rushes in through the openings i and j andpasses upward through the openings formed by the corrugated cones to theatmosphere, thereby forming a continuous upward draft, so that themoment the lamp is brought near the burner, as before described, the gasat once aims at the open space between the cones O and D and rushes intothe same, at the same time this rush of gas between the cone E andperforated cone D on account of the shape of the latter causes the flameof the lamp to take the direction of the arrows (Fig. 1), therebymeeting the gas and igniting the same. The perforated cone C performsthe further important duty of preventing the lamp from beingextinguished either by the sudden ignition of gas or excessive pressureof the atmosphere. The upper corrugated cones afford a further means ofpreventing the extinguishing of the lamp from the above causes.

By the employment of the inner perforated casing B, and by causing abody of air to pass through the openings in the exterior casing into thespace between it and the inner casing and through perforations in thelatter to the interior of the lamp, the outer casing is alwaysmaintained in a sufliciently cool condition to be handled with comfort.The lantern issubject to such frequent and violent agitation in thehands of the lamplighter that the flame from the wick of the lamp Kwould increase and consequently the might ensue if the hollow projectingcone L with its perforated top wasnot used. The gas or vapor generatedby the heat in the interior of the lamp passes through an opening intothe interiorof the hollow cone L,

I where it expands before it passes out of the minute orifice at thetop, whence it is either carried off by the draft and discharged intothe external atmosphere or it becomes ignited by the flame of the lamp,in which caseit will burn-with a small flame without any danger of thelatter communicating with the interior of the lamp, the peculiar shapeof the cone as well as its height prethe latter is in an inclinedposition or when it is agitated.

I Wish it to be understood that although I prefer three corrugatedcones, I do not desire to confine myself to'that precise number or formof cones as one cone only will 'serve the desired purpose and'as thecones 'may' be 'made plain instead of corrugated. heat would become sointense that explosions But What I claim, anddesire to secure by LettersPatent, is

Surmounting the body or casing of a lantern with ahollow perforated coneC situated within the exterior cone D in the manner and for the purposeherein set forth.

In testimony whereof, I have signed my name to thisspecification beforetwo subscribing witnesses.

ABEL WILSON.
